A clonal large granular lymphocyte disorder caused pancytopenia and marrow hypoplasia. Despite initial treatment success, the condition progressed, leading to organ infiltration and patient death.

Area of Science:

  • Hematology
  • Immunology
  • Oncology

Background:

  • Large granular lymphocyte (LGL) leukemia is a rare disorder characterized by an overgrowth of LGLs.
  • CD3+, CD8+ LGL leukemia can present with cytopenias and autoimmune phenomena.

Observation:

  • A 26-year-old male presented with pancytopenia and bone marrow hypoplasia.
  • The condition was associated with a CD3+, CD8+ clonal large granular lymphocyte population.
  • Initial treatment with cyclophosphamide and prednisone normalized blood counts.

Findings:

  • A relapse occurred with lymph node, stomach, and bone infiltration.
  • Steroids and combination chemotherapy proved ineffective in controlling the disease progression.
  • The patient ultimately succumbed to the illness.

Implications:

  • This case highlights the aggressive potential of CD3+, CD8+ clonal LGL leukemia.
  • It underscores the challenges in treating advanced or relapsed LGL leukemia.
  • Further research into novel therapeutic strategies for refractory LGL leukemia is warranted.
